This invention relates to improvements in mule spinning machines and has particular reference to improved means and method of winding yarn onto the bobbins of such machines.

One of the principal objects of the invention is to provide means and method of controlling the windings of yarn onto the bobbins of a mule spinning machine so as to provide a relatively short substantially continuously tapered wind at the start of said bobbins.

Another object is to provide novel means and method of controlling the shape of windings adjacent the head of the bobbins of a mule spinning machine by adjustment of the builder rail adjacent the rear thereof to alter the extent of movement of the mechanism of said machine which controls the position and amount of initial windings which are placed adjacent the head of the bobbins at the start of the winding operation and to provide means adjacent the front of the builder rail for compensating for the extent of adjustment of the rear of the builder rail in order to accomplish the above result and to insure the accurate positioning of the initial windings on the bobbins adjacent the heads thereof.

Another object is to provide an attachment for use in combination with a device for controlling the initial windings on the bobbins which will insure that the guide faller wires will accurately locate the intial windings in proper position on the bobbins.

Another object is to provide adjustable builder rail supporting means which will locate the initial windings of yarn onto the bobbins adjacent the head of the bobbins and simultaneously cause the windings to assume a short tapered shape adjacent said heads.

Another object is to provide improved means and method of quickly and easily adjusting machines of the above character so as to insure the production of the tapered initial windings adjacent the head of the bobbins whereby the percentage of yarn wastage which has hitherto been inevitable with automatic type weaving machines is greatly reduced.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawings and it will be apparent that many changes may be made in the details of construction, arrangement of parts and methods shown and described without departing from the spirit of the invention as expressed in the accompanying claims: I, therefore, do not wish to be limited to the exact details and steps of the methods shown and described as the preferred forms only have been given by way of illustration:

The invention relates particularly to the provision of attachments for use with mule spinning machines whereby differently controlled windings of yarn on the bobbins at the start of the winding operation may be formed.

It has been usual in the past, particularly for bobbins which are to be used with an automatic type weaving machine wherein the bobbins are automatically inserted in and ejected from the weaving shuttles during the operation of the machine, to build up the windings at the start 01' ad jacent the head of the bobbin so as to insure the provision of sufficient yarn to enable the shuttles to travel across the lathe or weaving head of the weaving machine and back after the automatic ejecting mechanism of such Weaving machines has been tripped and rendered ready to operate by a feeler which engages the wall of the bobbin just prior to the ejecting operation.

With the usual method of providing suincient yarn at the head of the bobbin, to enable the accomplishing of the above result, the windings at the head of the bobbin were so bunched that the yarn could not be drawn freely from the bobbin, causing undue breakage and resulting in excess wastage of yarn when the bobbins were ejected.

Many different devices have been employed for providing means for building up the yarn at the head of the bobbin, such as separate tapered members, which were attached to the up per surface of the builder rail, or means for holding the faller arm or faller arm roll away from the rail adjacent the rear end thereof at the start of the winding operation. Such prior art arrangements caused a bunched, tight winding to be formed, causing the above undesired re a sults of accidental breakage and excessive waste of yarn.

One of the prime objects, therefore, of the invention is to overcome the above difficulties by providing gradually substantially continuously tapered windings adjacent the head of the bobbin so that when the yarn is drawn from the bobbin during the weaving operation, the yarn will feed freely from the bobbin when a point is reached wherein the feeler of the automatic ejecting mechanism engages the wall of the bobbin and the shuttle then make its last trip across the operating head or lathe of the weaving machine back into the shuttle box from which the bobbin is ejected and a new bobbin is automatically placed in the shuttle. The gradually tapered windings are such that they allow the yarn to be drawn freely from the bobbin and thereby greatly reduce the tendency of the yarn to break as the end of the windings on the bobbin is approached prior to ejection and allows more of the yarn to be drawn from the bobbin with the result that a less amount of yarn remains on the bobbin when ejected from the shuttle and thereby greatly reduces yarn wastage.

The methodof operation of the mule spinning machine resulting from the device embodying the invention also greatly increases the eificiency of operation and production of such machines as it puts less strain on the yarn during the operation of building up the short tapered wind and thereby greatly reduces breakage of the yarn during said winding operation. The improved devices are such that the adjustments for bringing about the above result may be made separately or independently of the builder rail or shoe adjustments. None of the operating and adjustable parts of the present devices require detachment and may be quickly and easily adjusted without disturbing the general adjustments and operation of such machines.

Referring more particularly to the drawings wherein like characters of reference designate like parts throughout the several views the device to which the invention is embodied comprises a carriage I having a plurality of spindles 2 thereon for supporting the bobbins The spindles 2 are supported for rotation by means of a belt or the like 4 connected with a pulley 5 on the spindles and with a rotating drum or the like not shown. The rotation of the spindles 2 is by the usual means known in the art. The carriage I is provided with wheels which engage suitable ra-ils l for longitudinal movement toward and away from the supporting means 8 on which the spools 9 are mounted. The spools 9 have the yarn iii wound thereon. The said yarn is adapted to be drawn through suitable rollers E l and i2 and is connected to the spindles 2 adjacent the head of the bobbins. This is a conventional function.

Suitable guide wires, such as the guide faller wire 13 and tension faller wire id, are provided for controlling the position of the windings of the ends IE on the bobbins 3 and, also, for maintaining the desired tension on the ends during said winding.

The guide faller wire and tension faller wire are carried by suitable hook-like supporting arms l6 and H respectively attached to shafts l8 and N. The said shafts are rotatably mounted on suitable bearings carried by the supports 2| and 22 attached to the front of the carriage l. The shaft It, to which the arms 16, carrying the guide faller wire [3 is attached, is rotated to raise and lower the said guide faller wire by means of a faller arm 23. This faller arm is raised or lowered through it connection with a suitable roller 24 which engages a builder rail The builder rail 25 is attached to slide blocks 25 and 2'! slidably supported in upright guide members 28 and 2Q carried by suitable base plates 3i) and ti located in the front and rear of the machine, see Figs. I to IV inclusive. The guide blocks 2% and 21 are secured to the rail by connection bolts 32 and 33 which extend through the guide blocks 26 and 21 and through suitable bearings 34 and 35 internally of the front and rear end portions of the guide rail 25, see Figs. V and VI. The guide bolt 33 has a cam member 3 6 attached thereto which is adapted to engage the inclined surface 3i of a rear builder shoe 38. The cam 36 has a riser portion 39 which is adapted to be rotated in engagement with the cam surface 31 of the shoe 3%! by means of a lever ii) connected to the bolt 32 by means of a lock screw or the like 4!. The lever 40 is connected by a link member 42 to an upright 43 carried by a tie member 44 by means 'of which it is connected to a rod 115. The rod 45 extends forwardly and is connected at 46 adjacent the lower end of a rock lever 41. The rock lever 4'! is pivotally attached at 43 to an upright 49 carried by the base plate 30. The rock lever 41 is secured in adjusted position by means of a spring pressed plunger 59 which engages in suitable recesses 5! formed in the base plate 3% for lock ing the rock lever in forward or rearward adjusted position. A suitable grip lever 52 pivotally attached to the rock lever at 53 is adapted to raise the spring pressed plunger 56 to disengaged position with respect to the openings 5! in the base plate whereby the rock lever may be swung on its pivot 48 to draw the rod 45 forwardly or rearwardly as desired. When the rock lever 4'! is moved in a rearward direction, as indicated by the arrow 54, the rod 45 is drawn in a forward direction. This forward movement causes the upright 4 3 to draw the link member 42 forwardly and simultaneously rock the lever 43 in said forward direction and move the high spot 3% of the cam 36 down into engagement with the inclined abutment surface 3'! of the builder shoe 3%. This causes the slide block 21 to move upwardly of the slideway in the upright 29 and also causes the rear end of the builder rail 25 to raise the amount introduced by the throw of the cam 33.. It is apparent that the extent of movement of the rock lever 41 in a rearward direction controls the extent of raising of the rear of the builder-grail 25. The builder :rail 25 is'thereby moved to different inclined positions depending upon the .extent of movement .of the .cam 36. When ,the carriage is moved forwardly longitudinally of the rails I under the guidance of the wheels 6, which support the carriage I, the roller 24 which engages thebuilder rail 25 will cause the .faller ,arm 23 to be'raised or lowered the amount introduced'by the difference of pitch of the upper contact surface .of the builder rail 25. The carriage is moved forwardly by suitable means which is conventional in the art and the speed of movement is also controlled by .the usual conventional speed regulating mechanism ofrsuch machines. During the operation of the machine the carriage which is moved rearwardly and forwardly, as is usual in the art, and the mechanism for accomplishing this result is of the usual conventional prior art type which may be controlled .to regulate the speed and extent of movement of the carriage to accomplish the results desired.

The above described mechanism is of the conventional known type in the art and for this reason is not shown. A thorough description of one of the machines with which the device embodying the invention may be used can be found in a publication on High speed mules by Johnson & Bassett, Incorporated, Worcester, Massachusetts, which description is of the machine embodying the invention and is, therefore, part of the disclosure relied upon in this specification. The length of the rod 45 may be shortened or lengthened through the provision of a suitable turnbuckle 55, as illustrated in Fig. IV.

It is to be seen, therefore, that when the upper portion of the lever 41 is moved in a rearward direction the lower end 46, to which the rod 45 is attached, will draw the said rod 45 in a forward direction causing the cam 39 to raise the rear end of the builder rail 25 and vice versa.

It is to be understood that various different arrangements may be provided for controlling the extent of raising or tilt of the builder rail. The amount of lift or tilt is determined by the characteristics or the type of winding desired adjacent the head of the bobbins and it is through this adjustment of the height and tilt of the builder rail from adjacent the rear end thereof at the start of the winding operation which produces the substantially continuously short tapered winding.

The tapered windings which result from the builder rail adjustment and associated operating mechanism for bringing about this adjustment, .1

as shown at 56 in Fig. IX, is of a cone shape with the bottom of the cone adjacent the head 51 of the bobbin tapering upwardly and blending with the body of the bobbin 3, at a point upwardly of said bobbin ranging between A; to 1 /2" from the upper surface 58 depending upon the adjustment of the improved mechanism set forth above for controlling the characteristics of the windings.

The tapered windings result broadly from forming the first windings relatively close and with slightly more windings adjacent the bottom or head of the bobbin and gradually decreasing and slightly spacing the winding upwardly of the bobbin until the uppermost point or limit to which the tapered windings are to be formed is reached. The windings are then directed downwardly from said point andare caused'to be spread apart considerably as they progress downwardly toward the head of the bobbin. The

.next upward windings .are l in .close :relationiwith each other and simulate the. first upward-windings. This operation i repeateduntil the graduallytapered windings of the amount desired are formed adjacent'the base or head of the bobbin,

:as illustrated'in Figs. IX. It is to be understood that the spread :of the windingstheymovement of the carriage and the rotation of the :bobbin 3 is so controlled together with themovement of the guide fallerand tension wires I3-and l:4:-respectfully as tonaccomplish theresults desired, and it is particularly pointedoutthat the itapered windings described aboveresult from-.the altering of the pitchv or inclination of theupper surface of the builder-rail 25, as accomplished by the movement impartedto the rear of -.the builderrail. 25 by thecam member 36.

The builder rail 25 has a'so-called high :point 59at which point the upper surfaceof saidrail, as illustrated at 60, is inclined in a downward and forward direction the purpose of which-zwill be described more in detail hereinafter. It .is quite obvious that when the rear of the builder rail is raised the high point 59 of said rail will simultaneously be raised proportionately. This normally would throw the guide faller .wire t3 and tension faller wire I4 out of desired relation with the bobbin 3. To compensate for :this off adjusted position which resultsfrom the raising of the rear'end of the builder rail thereis provided a cam surface 6| on the connection bolt 33. This may best be seen in Figs. VI and VIII. The bolt "33 is supported'for rotation'internally of the slide block 26 and bearing'35 and is provided adjacentthe end'thereof opposite the builder rail 25 with a lever v62. The said'lever 52, as best shown in Figs. II and IV, is connected by a link member 163 to an upright 64 carried-"by a clamp block-65 attached'to the rod 45. The area of the connection bolt 33 at which the cam surface 6| is located is adapted to engage :the upper contour surfacet'o of the forward builder shoe 67. 'The saidshoe 61 having the bolt 33 resting thereon is adapted to'support theslide block 26 to which the forward end-of the-builder rail 25 is attached at its normal position'of use. When the-rear end of the builder rail 25,:however, is. raised by the cam'memberlifi as set-forth above, and the high point 59 of. said rail is simultaneously raised proportionately through 'the' forward movement of the tie .rod '45, as .:results through the movement impartedthereto -by:the rock lever .47, the upright 64 through itslink connection 63 with the lever 62 will simultaneously rotate the connection bolt :33. and cause the recessed cam surface 6| :to move intoengagement with the supporting surface 66 of the builder shoe "51. This causes the block 26 to move downwardly proportionately with the amount of recession of the cam surface 6|, which amount, is suflicient to compensate for "the amount which the high point 59 of the builder rail 25 is raised :when the rear end thereof is raised bythecam member 36. This, therefore,

repositions the guide 'fallerwire 13 and tension faller wire M in proper relation with the bobbins 3 so that the windings will start at their proper position adjacent the head 51 of the bobbin. The builder-shoes 38 and 61 are slidably supported on their respective baseplates 30 and 3|. The said builder shoes are connected by atie rod 63 whereby sliding movement imparted-t0 one of said builder shoes will simultaneously cause the other of said builder shoes to move proportionately. The said builder shoes are addownward inclination of said face.

justed by a suitable screw member 69 supported in a bearing I3 carried by the bed plate 30 and threadedly connected with the connecting blocks II carried by the tie rod 68. This is part of the conventional mechanism of such machines. The adjustment is accomplished through the coupling of a suitable crank member with the end 12 of the member 69.

' The adjustment of parts and the operation of the machine forbringing about the results desired is substantially as follows:

It is assumed that the doffing has been completed and that the ends I of the yarn to be wound on the bobbins is in initial positional relation therewith preparatory to starting the machine. The carriage I is now over the main face 13 of the builder rail as the carriage I is now in beyond the high point 59 of said rail according to the conventional operation of the machine. The face "I3 is normally inclined rearwardly and downwardly. This inclination is such as to cause the faller arm roll 24 and the said arm 23 to drop gradually as the carriage I completes its inward motion. This causes the guide faller wire I3 operated by the faller arm 23 to rise a controlled amount determined by the length of travel of the carriage 'I along the face I3 and the pitch of the This is a normal setting for completing the building up of the windings on the bobbin after the desired a short windings are formed adjacent the head of the bobbins.

In carrying out the present invention and to form the initial short tapered windings adjacent the head of the bobbins, the rear end of the builder rail 25 is elevated a controlled amount. This is accomplished by the adjustment of the lever in a forward direction which rotates the high spot 39 of the cam 36 into engagement with the surface 3'! of the builder shoe 38. This is accomplished through the manipulation of the upper portion of the rock lever 4! in a rearward direction as illustrated in Figs. I, II and IV and the extent of adjustment is such as to change the pitch of inclination of the face I3 the proper amount to cause the guide faller wires I3 to move upwardly of the bobbins 3 a restricted controlled amount of approximately to 1 /2", more or less, according to the setting brought about by the rock lever 41 when the carriage I is first moved inwardly. It is to be noted that the front end of the builder rail, that is, the inclination of the face adjacent the front of the rail is changed or slightly increased from its normal angle by said adjustment.

Simultaneous to the movement of the high spot 39 of the cam member 36 into engagement with the surface 31 of the builder shoe 3B the recessed cam surface 6| of the bolt 33 is moved into engagement with the contact surface 66 of the forward builder shoe 61. This compensates for the upward movement of the high point 59 of the rail which takes place during the raising of the rear end of the rail and the amount of compensation is such as to cause the guide faller wire I3 and tension faller wire I4 to return to desired positional relation with the bobbins 3 and they will thereby cause the windings to start on the bobbins at the proper position adjacent the heads thereof.

' As stated above, as the guide faller wire I3 moves upwardly of the bobbin, when the carriage I moves inwardly, as controlled by the pitch of the surfaces 60 and I3 respectfully of the builder rail, the windings on the bobbin during this upward movement of the guide faller wire I3 will be relatively close at the start and will separate slightly as the guide faller wire approaches the full extent of its upward and restricted movement as determined by the pitch of the surfaces 60 and I3. The faller arm 23 is then disengaged from the roller 24, causing the guide and tension wires I3 and I4 to move upwardly and simultaneously to wind loose yarn to the top end of the bobbin at which position the bobbins cease to rotate.

The carriage I is then ready to move outwardly or forwardly with the usual mechanism functioning to feed the loose yarn II! from the spools 9. As the loose yarn is fed from the spool, the outward movement of the carriage I draws and twists the yarn. This twisting is caused by simultaneous rotation of the bobbins.

Due to the fact that the faller arm 23 and roller 24 are disengaged, the guide and tension wires I3 and I4 remain stationary adjacent the upper ends of the bobbins and thereby prevent any winding of yarn on said bobbins. The rotation of the bobbins, therefore, merely twists the yarn.

When the carriage I nears the limit of its outward or forward movement the twisting operation is completed by further rotation of the bobbins a controlled amount. When the twisting is completed, and before the winding operation can begin, the small amount of yarn between the top of the bobbin and the yarn already on the bobbin must be unwound. To do this the spindles 2 carrying the bobbins must be revolved in the opposite direction for a few turns. This motion is termed the backing off and is the usual motion imparted in the art of spinning.

The tension and guide faller wires I3 and I4 are then operated by their usual known operating mechanism and simultaneously move the guide faller wire I3 downwardly to take up this slack of yarn removed from the bobbin during the backing off. The guide wire I3 moves downwardly to a point adjacent the upper end of the first winding.

As the guide wire I3 goes down the faller arm 23 goes up until it reaches a point where it is moved into interlocked relation with the faller arm roll 24. This engagement takes place after the twisting operation has been completed and at the position at which the carriage is located as the result of its being eased in during the twisting operation. This interlocking of the faller arm with the faller roll, at this location, takes place through the usual mechanism provided with such machines. When the faller arm and roll are interlocked, the roll will be resting on the inclined surface 60 adjacent the front end of the builder rail 25.

The machine is then ready to start its second Wind. As the carriage I moves inwardly the faller arm roll 24, engaging the sharply inclined surface 60 at the front end of the builder rail, causes the guide faller wire I3 to move downwardly quite rapidly causing the windings in the downward direction of the bobbins to be spread considerably until the lowermost position is reached. This lowermost position is reached as the faller arm roll 24 rides over the end 59 of the sharply inclined surface 60 onto the main surface I3 of the builder rail. The main surface from this point, due to the adjustment brought about by raising the rear end of the builder rail through rotation of the cam 36 to move the high spot 39 thereof into engagement with the inclined surface 31, will be slightly inclined downwardly a controlled amount as previously described above.

This causes the faller arm 23 to move downwardly and move the guide faller wire I3 gradually upwardly. At the start of this upward movement, the carriage moving mechanism is such that the carriage l moves in slowly causing the guide faller wire I3 to likewise move slowly upwardly. Due to the fact that the bobbins 3 are simultaneously being continually rotated in the direction of winding, more windings will be made on the bobbin adjacent the bottom. These windings are gradually directed upwardly of the bobbin as the carriage moves in and as the guide wire l3 simultaneously moves upwardly. The speed of the carriage gradually increases as it continues to move in and thereby causes the guide wire l3, operated by the downward movement of the faller arm 23, as brought about by the degree of rearward inclination of the main face 13 adjacent the innermost end thereof, to move upwardly with more speed and thereby reduce the windings and increase the space between said windings. The said spaced windings continue until the carriage reaches its innermost position.

This operation is repeated again with the result that cone shaped windings 56, as shown in Fig. IX, are formed adjacent the head 51 of the bobbins. This operation is repeated until the desired amount of short windings are formed. There may be more or less short windings put on if desired.

The new mechanism is then disengaged by operation of the rock lever 41 in the opposite direction to move the high spot 39 of the cam 36 upwardly out of engagement with the inclined surface 31 and thereby allow the rear end of the rail to drop to its normal position of use. The machine is then operated to complete the usual windings which fills the bobbins.

The bobbins are then removed and transferred for use in weaving looms. The looms with which such bobbins are used, are of the usual automatic type wherein the bobbins are automatically positioned in and ejected from the Weaving shuttles during the operation of the loom.

With the tapered wind 56 adjacent the head 51 of the bobbin, as made by the present invention, only a relatively small amount of yarn remains on the bobbin when ejected from the shuttle. This is due to the fact that the yarn is allowed to be removed from the bobbin to a point adjacent the base of the taper prior to the operation of a device known in the art as a feeler 14, which causes the ejecting mechanism to function. The feeler does not operate until it engages the bare solid side wall of the bobbin and this engagement only takes place after the yarn has been fully removed from the area 15 which aligns with the feeler. When the area has been stripped of its windings, the feeler operates but the ejection does not take place until the shuttle travels across the lathe or head of the loom and returns back to the shuttle box at which the bobbin is ejected from the shuttle.

It is apparent, therefore, that sufficient windings must be on the bobbin to permit this to take place. The tapered winding, as made by the present invention, is such that it not only provides the necessary amount of windings, but also allows the said yarn to be easily drawn from the bobbin. The tapered windings are such that accidental breaking of the yarn, prior to the ejection of the bobbin, is substantially eliminated and causes only a slight amount of yarn to remain on the bobbin and thereby eliminates undesired waste. This latter result is one of the outstanding features of the invention and overcomes the difiiculties encountered with most prior art arrangements.

The inclination of the face 13, when in its normal prior art position of general use, is relatively steep as compared with the change of inclination brought about according to the present invention. The normal inclination has been such as to cause the guide faller wire l3 to raise quite quickly and form substantially uniformly distributed windings throughout its span of movement. The inclination of the face 60, when in its normal prior art position of general use, is relatively less than when changed according to the present invention so that the usual windings in the downward direction were normally greater and closer than those resulting from the present invention. The increase of inclination of said face 60 resulting from the arrangement embodying the invention, reduces and increases the spacing of said downward windings due to the relatively quick rise and resulting quick drop of the guide faller wire which controls the position of the windings on the bobbin.

The windings resulting from the arrangement embodying the invention will be less at the top of the taper because the guide faller wire moves down with greater speed, due to the increased incline of the face 60 and more windings are formed at the bottom or base of the taper because of the relatively slight inclination of the face it which has been decreased by the device embodying the invention, as stated above, and through the tendency of said slight inclination to cause the guide faller wire to move upwardly much more slowly at the start, resulting in more windings being formed at the base of the bobbin. This is because of the relatively slow reversing movement of the guide faller wire brought about by the traversing of the high point 59 onto the face 13 at the start of the upward windings and the speed of inward movement of the carriage I is relatively slow at the start, as stated above. This slow inward movement of the carriage, and

the increasing of the speed of the carriage after.

it has started its inward movement, combined with the decreased speed of upward movement of the guide faller wire, as brought about by the reducing of the inclination of the builder rail, all contribute to the forming of the short tapered wind 2. It is to be understood that although more windings are being formed at the base of the bobbin, said windings are gradually in an upward direction so that when the last of the windings are being removed from the bobbin in the weaving loom, the said yarn will flow freely from the bobbin. The angle of the face 60 may be changed, if desired, by adjustment of the screw or the like 16.

Due to the fact, therefore, that the windings progress upwardly a substantially continuous taper wind will be formed.

From the foregoing description it will be seen that simple, efiicient and economical means and method have been provided for accomplishing all of the objects and advantages of the invention.
